* Boardwalk Empire” (Sunday, 9 p.m., HBO) At least last week’s episode gave us the welcome return of Chalky (Michael Kenneth Williams) — aka Omar — who disappeared for too many weeks after he handled the Klan. This week, Nucky takes a road trip to Chi-Town to vote early and often at the Republican National Convention. Mama’s pretty sure she couldn’t pick Warren G. Harding out of a lineup, but we should probably expect to get a glimpse of the future 29th president. And as a bonus, maybe Jimmy and Nucky might share a scene again.

* “Days of Our Lives” (Monday, 1 p.m., NBC) It’s never been Mama’s cup of dish soap, but she has to admit that as “Days” celebrates its 45th anniversary, it is not only one of the last remaining old-school daytime dramas, but has consistently remained loyal to its core families and their history. Sure, the history includes demonic possession, but what family doesn’t have a few skeletons?

* “One Tree Hill” (Tuesday, 8 p.m., The CW) Apparently, this show might still be about basketball — Tony Gonzalez of the Atlanta Falcons appears in a cameo role — and not the aging teen stars’ struggles to score affordable daycare.

* “Parenthood” (Tuesday, 10 p.m., NBC) If you want to know how your network really feels about you, check your guest-star list during sweeps. “Parenthood” gets “Friday Night Lights’” Michael B. Jordan — a great actor, yes, but a sweeps star from your network’s red-headed stepchild? Gives you some idea of the pecking order for “Parenthood.”

* “Grey’s Anatomy” (Thursday, 9 p.m., ABC) Peter MacNicol, he of “Ally McBeal” fame (is it still fame if the series has been off the air for nearly a decade?) guest stars as Dr. Phil Stark. Yes, it’s come to this.

* “Fringe” (Thursday, 9 p.m, Fox) Our Olivia needs to get back to our universe soon, as Faux-livia and Peter’s romance heats up this week.
